Description

The TL16C554PNG4 is enhanced quadruple versions of the TL16C550B asynchronous communications element (ACE). Each channel performs serial-to-parallel conversion on data characters received from peripheral devices or modems and parallel-to-serial conversion on data characters transmitted by the CPU. The complete status of each channel of the quadruple ACE can be read at any time during functional operation by the CPU. The information obtained includes the type and condition of the operation performed and any error conditions encountered. TL16C554PNG4 Features • Integrated Asynchronous Communications Element• Consists of Four Improved TL16C550 ACEs Plus Steering Logic• In FIFO Mode, Each ACE Transmitter and Receiver Is Buffered With 16-Byte FIFO to Reduce the Number of Interrupts to CPU• In TL16C450 Mode, Hold and Shift Registers Eliminate Need for Precise Synchronization Between the CPU and Serial Data• Up to 16-MHz Clock Rate for up to 1-Mbaud Operation• Programmable Baud Rate Generators Which Allow Division of Any Input Reference Clock by 1 to (216−1) and Generate an Internal 16 × Clock• Adds or Deletes Standard Asynchronous Communication Bits (Start, Stop, and Parity) to or From the Serial Data Stream• Independently Controlled Transmit,Receive, Line Status, and Data Set Interrupts
